Baidu Markup Checker
Report the page-level signals Baidu reads -- and what Baidu publishes no specification for.
Baidu publishes no open structured-data specification: its rich results come from programmes on the Search Resource Platform that a site is invited into and submits data to, not from an on-page vocabulary anyone can implement. So this reports the signals that are observable and that Baidu demonstrably uses, and does not claim to predict a Baidu rich result.

About this validation
Reports the page-level signals Baidu reads. Baidu publishes no open structured-data specification: its rich results come from programmes on the Search Resource Platform that a site is invited into and submits data to, rather than from an on-page vocabulary anyone can implement. This tool therefore reports observable signals and does not claim to predict a Baidu rich result.

SEOTechTests methodology: Reports the page-level signals Baidu is known to read -- the Search Resource Platform verification tag, the mobile-adaptation tags, title, description, declared charset and canonical -- and whether any vendor-neutral structured data is present. It scores coverage of those signals and never implies a Baidu rich result, because Baidu publishes no specification to check one against.
Standards and vendor-documented behavior can change. This reflects the source as last reviewed above, not a permanent guarantee.
FAQ
Does Baidu support schema.org?
There is no current Baidu specification that says so. Third-party guides claim it, and the claims trace back to announcements that are more than a decade old. This tool reports structured data as present rather than as satisfying a Baidu requirement.[1]
Why is there no Baidu structured-data score here?
Because there is nothing published to score against. Baidu's structured-data programmes run through submission and invitation on the Search Resource Platform rather than through an open on-page vocabulary, so a tool claiming to validate Baidu markup would be making its rules up.[1]
What actually helps a page in Baidu, then?
The observable basics this tool checks: a claimed site, an explicit charset, a clear title and description, a canonical, and a declared device target so Baidu's mobile adaptation does not transcode a page that is already responsive. Crawler access is a separate question -- the Robots.txt Checker covers Baiduspider rules.[1]
